WWE Superstar Roman Reigns solemnly announced that his leukemia is back.

Fans immediately reacted on social when Reigns made the announcement on 'Monday Night Raw,' revealing that he wouldn't be able to carry out his responsibilities as a wrestler, relinquishing the Universal Championship.

Speaking to fans who were clearly shocked and distraught, he also announced that he would be going home to focus on treatment and vowed to overcome the disease that he has been fighting for over a decade now.

I will beat this, I will be back, and you will see me very, very soon.

WWE released this statement shortly after the announcement.

Tonight on Monday Night Raw, Roman Reigns (aka Joe Anoa’i) announced that he is relinquishing the WWE Universal Championship and taking a leave of absence from WWE as he once again fights leukemia, which had been in remission since late 2008. Reigns is taking his battle with leukemia public in an effort to raise awareness and funds for research in order to advance cures for the disease.
